I bought this 93' prelude throtle body from a friend. He had it put

on his 94' intergra. Anyways we install it and now when my car is

idling my RPMs fluctuate from 1000 to 1500 RPM. I have a

Tannabe Racing Medalion so it's pretty loud and annoying.

I have a 97' integra. I asked my friend about the fluctuation and

he said that it would fluctutate when he first installed it but he said that

after a while it went away. What the deal with this? Is it good

for my engine the way it revs up and down for no reason.

thanks

 

Reset your ecu and see if it goes away. I had a similar problem when I installed a B18C5 motor in my car and did not reset the ecu. I thought because it was not much different there would be no problems but after I reset the ecu. The idle smoothed back out.

I already tried that. I tried the throtle body screw adjustment but it did not do anything.

 

maybe it is the TPS

 

How long did you wait after you reset it? If you tried the standard procedure of pulling the ecu for 10 minutes, starting it(don't touch gas) and let it idle for like 5- 10 minutes and it still does this then it may be another sensor or distributor.

 

When I turn on my car the idle doesn't fluctuate i let it sit there for a while and when i give it gas it just goes
VROOOOOMMMM vrooooooooommm VRRRRRRRRRROOOOOOOM vrrrooooomm etc.

This sux

 

mine does the same thing, when I first start it its fine but after it starts to warm up it goes like its about to die out but then comes right back.
